Have you tried logging out and then back in again? Is it just Stock that is in the wrong language or the entire CC?
Thanks for the help. I will try that after I resolve my core problem. I have several tabs open I'll lose if I do that. Would you happen know how I can download stock photos I purchased without the watermark. That is more core problem.
Regarding language setting: look for a drop down that allows you to pick the language. Problem solved
